He decides to have an "incubus" , which is a fancy term for an in-betweener . The narrator tells his mom all about his life, and she's all, "Oh, yeah, that's awesome. I'm so glad you're so into me." The narrator then tells her a little story about how he and his friend, a young man named rin, have been in love for a year and a half, and how rin is now planning a trip to celebrate rin's birthday. .
